[XPE-SP3] Component FootPrint "Japanese bitmap & TrueType fonts"

Hello,

I'm migrating from Windows XP Embedded SP2 FP2007 to SP3.
The initial Footprint of my OS image was increased a lot with SP3.

I would like to know if all the files found in the new "Japanese bitmap &
TrueType fonts" component version are absolutely necessary.
The old huge component files were:
msgothic.ttc
msmincho.ttc

The added huge files are:
msgoth04.ttc
msmin04.ttc

Are these last tow files absolutely necessary to use this Japanese font?

Thanks in advance
